I’m looking to replace my current table-mounted plunge router (Chicago Tools 3.5HP 19A) with another beastly router of far superior quality. I’m considering the Porter Cable 7538 because I already own a router speed control from MLCS.

The Chicago router immediatedly jolts up to maximum RPM when turned on, so I use the speed control to soft start it and adjust to the desired speed (the real reason for my wishing to replace it is because when I try to use panel raiser bits or a bit extension shaft, the whole router makes a frighteningly loud vibrating noise which I think means a crooked shaft or bad bearings). The PC router claims to have soft starting built in, but I still want to use my variable speed control WITHOUT HAVING TO REACH INSIDE MY ROUTER TABLE to adjust speed on the router motor like Norm Abram’s 7539 5-speed router.

Is it worth saving approximately $40 to buy the single speed soft-start router and use my own variable speed control with it? Are the two even compatible (meaning: will the soft-start router even work with the v-s control?)

Any input or personal experience is appreciated.

Some routers (I believe soft start routers fall into this category) are not compatible with external speed controls. Be sure and check before you invest in one. I have a Freud 2.25hp and it is not compatible.

IF no soft-start routers are compatible with external variable speed controls, does anyone know of a modern 3HP router (besides Chicago brand) that is premium quality, yet has no soft start or variable speed built in?

The variable speed comes in very handy even if you have to change the speed manualy on the router. In real terms I personally rarely ever change the speed of my table mounted PC except when using VERY large bits then I slow it down a little. Most of the time I am using a mid range speed on the router for everyday use and average sized bits.
